Multiple times I've come across issues like this when developing the replacement for an old access system. The numbers between the new an old system don't match, so you have to dig through both to find the error. If the error is in the new version that's great, but when you tell the boss that the error is in the old one and they've been off by a few million dollars over the years...

However, development costs are so expensive they might have broken even when factoring the cost of creating a system.
